[QUOTE="kme, post: 217610, member: 113"] Hi Sarah. Although some electricians will have sound level meters, they may only be useful for locating where the sound is loudest; which it sounds like you`ve already done. There is equipment which can determine the frequency of the sound, which can be useful in determining a likely cause - but it is relatively specialised to sound engineers and so forth. If you`ve turned off all your electric & water, and the sound persists, it is likely to be external to your property - either a neighbour`s flat, or outside; and as such is out of your control. Other than asking the neighbors whose property shares a wall with your bedroom to turn their electric/water off; there isn`t a lot you can do, except possibly soundproofing. The problem could be that, if the sound is within the building, and is being transmitted through the walls, soundproofing won`t help. The only other thing that springs to mind - which might possibly work, involves knowing the [I]exact[/I] frequency of the sound, and generating the same frequency yourself, out of sequence with the existing noise. They would tend to cancel one another out - meaning you don`t hear either of them. However, the equipment needed for such a solution would be costly..... Sorry I can`t be more help. KME [/QUOTE]
